Now that I'm looking for it, I believe I can confirm there is 1-2 seconds of silence when resuming from pause seeking (on ION2) - presumably this is the same issue you refer to with forward/rewind. I'll need to confirm later when it started (no more time for Kodi until later this evening). I've not noticed the sound being quieter, but will do some A/B testing this evening.

Edit: Correction, seeking not pausing.
Edit2: "audio silence after seek" definitely starts with #0910, probably PR12785. Not hearing any difference in volume though, sounds the same to me.
